Forbearance and deferment both pause loan payments temporarily, and both get granted for similar reasons, things like job loss, medical hardship, or a return to school. The difference that actually matters sits in what happens to interest during that pause, and it can shift the total cost of a loan by thousands of dollars depending on which one applies.
During deferment on certain federal student loans, specifically subsidized loans, the government covers the interest that would otherwise accrue, meaning the loan balance does not grow during the pause. Forbearance offers no such protection. Interest keeps accruing the entire time, on every type of loan, and it gets added to the principal balance once payments resume.
Why the Interest Difference Compounds Over Time
A borrower who takes twelve months of forbearance on a loan carrying six percent interest sees that unpaid interest capitalize, meaning it gets folded into the principal balance, once the forbearance period ends. Every future interest calculation then runs against a larger number, permanently, not just for the months the pause lasted.
Deferment on subsidized loans avoids that entirely, which is why it gets prioritized over forbearance whenever a borrower qualifies for both. Unsubsidized federal loans and most private loans do not get the same interest coverage during deferment, so the practical difference between the two options shrinks considerably outside the subsidized loan category.
Loan servicers are not always upfront about steering borrowers toward the option that costs less over time, since forbearance is usually easier and faster to approve than deferment, which comes with more documentation requirements tied to specific qualifying circumstances.
When Each Option Actually Applies
Deferment generally requires meeting a specific qualifying condition, such as enrollment at least half time in school, active duty military service, or unemployment that meets certain criteria. Forbearance has a lower bar and can often be granted for general financial hardship without the same documentation.
Borrowers should always check deferment eligibility first, specifically for subsidized loans, before accepting forbearance as the default option a servicer offers first. That single question, asked directly to the servicer, can be the difference between an interest free pause and one that quietly grows the loan balance.
For anyone already thinking ahead to how a pause fits into a broader repayment strategy, comparing it against other student loan repayment strategies for the loan overall, rather than treating the pause as an isolated decision, tends to produce a better long term outcome.
What to Do Once Payments Resume
Making interest only payments during a forbearance period, even without an obligation to do so, prevents that interest from capitalizing once the pause ends. Most servicers accept voluntary payments during forbearance, and even small amounts applied toward accruing interest can meaningfully reduce the eventual jump in balance.
Checking the new payment amount and loan balance immediately after a forbearance period ends catches capitalization errors early, since servicers occasionally miscalculate the new balance, and those errors are far easier to fix close to when they happen than months later.
Private student loans handle both forbearance and deferment very differently from federal loans, and the terms vary significantly from one lender to another with far less standardization than the federal system provides. Reading the specific promissory note for a private loan, rather than assuming it follows federal rules, avoids a lot of confusion when a hardship request gets processed differently than expected.
Mortgage and auto loan forbearance, which became widely available during periods of broad economic hardship, generally work on a repayment or modification basis once the pause ends, rather than simply resuming the original payment schedule with a lump sum due. Understanding which repayment option a specific loan uses before entering forbearance avoids an unpleasant surprise once the pause period concludes.
Documenting every conversation with a loan servicer, including the date, the representative’s name, and what was agreed to, creates a paper trail that becomes valuable if a servicer later disputes what type of hardship program was actually granted. This habit costs almost nothing and has saved plenty of borrowers from servicer errors that would otherwise be difficult to prove after the fact.
Income driven repayment plans offer another path for federal student loan borrowers facing hardship, one that adjusts the monthly payment based on income rather than pausing payments altogether. For a borrower whose hardship is more about affordability than a complete inability to pay anything, switching to an income driven plan sometimes makes more sense than either forbearance or deferment, since it keeps the loan actively being paid down rather than accruing unpaid interest during a pause.
Loan servicers change periodically as loans get sold or transferred between companies, and a hardship arrangement agreed to with one servicer does not always transfer cleanly to the next one handling the account. Confirming that a forbearance or deferment agreement carried over correctly after any servicer transfer avoids the unpleasant surprise of a payment coming due that the borrower believed was still paused.
